The data collected from Israel's adverse events reporting system showing that some women experienced menstrual disorders for more than 12 months after receiving a COVID-19 vaccine raises concerns, according to Dr. Shelly Cole, an obstetrician-gynecologist in Texas.
“Looking at the Israeli data is very concerning,” Cole told The Epoch Times.
Of the 282 Israeli women who reported menstrual abnormality following COVID-19 vaccination, 88 reports contained information on the duration of the condition. And of the 88 reports, 83 disclosed that the menstrual problems lasted over a week. Some of the women's problems had still not resolved.
All but one of the reports were from adults. The single child report detailed a disorder lasting between one and six months.
Of the other 82 reports, 11 reported that their condition lasted between one week to one month, 42 that their condition lasted one to six months, 22 that they suffered for six to 12 months, and seven that their condition lasted for over 12 months.
Health experts say the actual number of menstrual cases is much higher than what is being reported to the system and others like it. Many women may have thought that their condition was not vaccine-related, been unaware of the reporting system, or not been encouraged by their doctor to lodge a report.
Cole said that she wasn't surprised that women were complaining of irregular menstruation, including abnormal bleeding following vaccination. She's seen it “throughout the pandemic" in her clinic and discussed the matter with other doctors.
The MoH used the total vaccine doses administered since the shots were cleared—over 18 million—as a denominator to calculate the risk of adverse events. The shots were cleared in late 2020, but the new reporting system was not launched until December 2021.
“They took the 18 months of doses of the Pfizer vaccination and they only looked at the side effects for six months,” Cole said. “So how can this be even remotely valid?”
That minimized the calculated risks of the adverse events reported, including menstrual abnormalities. And they included doses given to males when calculating risks despite men not menstruating.
“They minimized menstrual irregularity by implementing men in the data," Cole said.
The MoH did not respond to The Epoch Times' request for comment.
PresentationThe MoH commissioned a group of researchers to analyze reports of adverse events submitted to their new reporting system following vaccination from December 2021 to May 2022. The researchers found that the duration of some events, including menstrual disorders, were not short-lived or mild as health authorities claim.
The researchers also said that Pfizer officials informed them that the company was unaware of any long-term symptoms.
Pfizer didn't return multiple emails requesting comments.
Sasha Zhurat, the main presenter at that time, said that many of the complaints of menstrual abnormalities lasted for several months and not the couple of days that is mentioned in the brochure distributed to vaccine recipients.
“But compared to the leaflet where it says that the symptoms go away after a few days, we saw that there were many reports, and only 5 percent had symptoms that lasted between two weeks and a month, all the rest were much longer,” Zhurat said.
She added that “over 90 percent of the reports in which there appears some kind of topic of duration and long-term changes,” 60 percent reported a change lasting three months.
In 10 percent of these women, Zhurat said that they experienced the same menstrual issue following additional vaccine doses, a phenomenon known as rechallenge.
Rechallenge is one factor to establish causality between a vaccine and an adverse event when the re-administration of the same vaccine causes the reoccurrence of a side effect that had gone away.
Some side effects are officially recognized by vaccine makers and health authorities, such as heart inflammation. But the researchers discovered that some others were also caused by the shot.
Some of the findings, including the finding of rechallenge, were omitted from the MoH's report to the public.
StudiesAfter the rollout of the messenger RNA COVID-19 vaccines, many women around the world also began reporting menstrual changes.
“In this sample, 42 percent of people with regular menstrual cycles bled more heavily than usual, while 44 percent reported no change after being vaccinated,” the authors wrote. “Among respondents who typically do not menstruate, 71 percent of people on long-acting reversible contraceptives, 39 percent of people on gender-affirming hormones, and 66 percent of postmenopausal people reported breakthrough bleeding.”
The authors called for further studies on post-vaccination changes to a woman's menstrual cycle and to determine the causes of the changes.
